WINDOW GUARD.

Application filed June 30, 1922.

To all whom it may concern:

Be it known that I, STANLEY SKURNIAK, a citizen of Poland, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in IVindow Guards, of which the following is a specification.

This invention relates to protective devices for banks, stores, booths, etc, whereby the persons behind a counter or window, or in a booth, are protected against attacks byrobbers.

The object of the present invention is to provide a vvery eficient and reliable device of the kind stated and to this end it consists in a novel combination and arrangement of parts to be hereinafter described in detail and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawings, wherein:

Figure 1 is an elevation of the structure to which the invention is applied; Fig. 2 is an enlarged vertical section on the line 22 of Fig. 1; Fig. 3 is a horizontal section on the line 33 of Fig. 1; Fig. 4 is an enlarged horizontal section on the line 4-4 of Fig. 2; Fig. 5 is across section on the line 5-5 of Fig. 4; Fig. 6 is a sectional detail on the line 66 of Fig. 3; Fig. 7 is an elevation of a fragment of the protective curtain; Fig. 8 is a vertical section on the line 88 of F ig. 7; Fig.9 is a cross-section on the line 9-9 of Fig. 8; Fig. 10 is an elevation, partly in section, showing another embodiment of the invention; Fig. 11 is a horizontal section on the line 11-11 of Fig. 10; Figs. 12 and 13 are vertical sections on the lines 1212 and 13-13 of Fig. 10; Fig. 14 is an elevation of a detail; Fig. 15 is a vertical section on the line 1515 of Fig. 14.

Figs. 1 to 9 show the invention applied to the window of a bank or other office. The jambs of the window are shown at. 20, and near the bottom thereof is a door 21 for entrance to and exit from the room, compartment or the like. The protective device is a curtain 22 made up of perforated metal strips which are hingedly connected to ob tain suificient flexibility to permit the curtain to be wound on a roller 23 and to be unwound therefrom. This roller is located at the bottom of the window, inside the room, compartment or the like, and below the floor 24 h f. The curtain 22 is suit Seriafl No. 571,889.

ably fastened at one end to the roller 23, and to the other end of the curtain are made fast hauling lines 25 which extend upwardly to guide pulleys 26 at the top of the window, and after passing over the latter, said lines extend downwardly and have weights 27 connected to their lower free ends. When the curtain is not in use, it is rolled up on the roller 23, and so held by a means to be presently described. The winding of the curtain on the roller elevates the weights 27, and when the curtain is released the weights descend and draw the curtain off the roller to close up the window, the curtain traveling upwardly as the weights descend. The weights and the hauling lines seat in housings in the jambs 20, and in the bottom of these housings are located spring bumpers 28 which are engaged by the weights at the limit of their downward travel. Adjacent to the roller 23, and parallel thereto is a cutting guide roller 29.

The curtain 22 is held wound on the roller 23 by a brake band 30 engageable with a. brake drum 30 on one end of the shaft 23 of the roller. One end of the brake band is anchored to a support 31 and its other end is fastened toa coiled spring 32 which operates to tighten the band around the drum. The spring is anchored to a suitable support 33. The last-mentioned end of the brake band is also connected to the outer end of a rocker arm 34 extending laterally from a rock shaft 34 to which is connected one end of a lever 35 having connected toits other end the stem 36 of a foot pedal 37, said stem passing upwardly through a hole in the floor 24 to locate the pedal close to and above the latter. The rock shaft 34 also has a rocker arm 38 extending in the opposite direction from the arm 34, to which arm 38 is connected a coiled spring 39 anchored to the floor 24, beneath the latter. It will be evident from the foregoing that when the pedal 3? is depressed, the lever 35 swings in a direction to cause the arm 34 to expand the spring 32 and thus allow the brake band to slackenand release the drum 30 whereupon the curtain 22 is released and unwound from the roller 23, and drawn upwardly to operative position by the weights 27 Upon releasing the foot pedal 37, the spring 39 restores the same to its normal position, and the brake band again grips the drum.

The winding gear whereby the curtain "ill 2 is rowound on the roller 23 comprises be following parts:

One end of the roller shaft 23 is fitted with a bevel gear e which is in mesh with a bevel gear 47-1 on a shaft 42 having one of its ends jonrnaled in an axial recess in the adjacent end of an axially alined shaft dB, The shafts and a l-are connected to turn together. and the shaft 42 is slidable in the direction of its length to take its gear I out of mesh with the gear i-iO, this operation being effected by a'shifter 2 connected by a link to a crank arm 46 on a tubular vertical shaft 47 i'tted at its upper end with an operating handle :8 provided with a catch l to lock the same. Through the shaft -17 extends a shaft 50 having its lower end fitted with a bevel gear 51 which is in m esh'with a bevel gear 52 on the shaft 43. The upperend of the shaft 50 is fitted with a bevel gear 51 which is in mesh with a' bevel gear 52 on the shaft of a crank handle 53. The gears 51 and 52 are enclosed in a housing a mounted on the wall of the oflice or other compartment to which the invention is' applied.

Upon swinging the handle $8 in the proper direction, the shaft 42 is slid to disengage its gear 4:1 from the gear 40. This will be the normal position of these parts. If new it becomes necessary to use the curtain; the foot pedal 37 is depressed, whereupon the brake mechanism hereinbefore described releases the roller 23 and the ciu-tain 22 is at once drawn upwardly to protective position by the weights 27'. To

rewind the curtain on the roller, it is necessary only to shift the shaft 42 in a direction to bring its gearelin mesh with the gear etll and then to operate the crank handle 53, whereupon through thegearing hereinbefore described the roller 23 is rotated to wind the curtain thereon;

Figs, 7 to 9 illustrate the connection between the curtain 22 and the hauling lines 25. One end only of the curtain has been shown, it being understood that the fixtures at the two ends are alike. To the free end or the top of the curtainareriveted two outwardly facing angle bars 55, the flanges of these bars being cut away near the ends to permit a pair of bracket menr' hers 56 to be riveted. thereto, The upper ends of tLese bracket members carry a cross pin 57. TAG end of the line 25 is formed into an eye 58 through which the cross pin 57 passes. Below the cross pin 57, the bracket members 56 carry anti-friction rollers 59 which run on the opposite side walls 60 of a guide channel mounted on the jainb 20.

Figs. tto disclose a counter or show case guard consisting of a curtain which trav ls downwardly to protective position.

This curtain is fastened to a winding roller (51 suitably supported at the top of the structure. In front of the roller 61 is a o. ide roller 62 over which the curtain pa ses. To the Bottom of the curtain, at each end thereof, is fastened a weight 63 the connection being made by bracket plates (3-iequipped with anti-friction rollers Gl which travel in guide channels 65. The weights 6-3 are located beyond the side edges of the curtain to travel in. a housing 63 containing a spring bumper 65 which is engaged by the weights at thelimit of the downward travel of the curtain.

The curtain fi l is held, wound up on the roller 61 by a brake band (56 passing around abralre drum 6? on one end of the roller shaft 68. its in the structure first describedi the brake band is held tauthy' a spring: 69, and released by a rod 70 extendingdownwardly therefrom, its lower end being operatively connected to a' foot rail 7T so that when the latter is pushed forwardly, the brake is operated to release the' roller 61 and allow the curtain'GOto be unwound and pulled downwardly by the weights 63.

The roller shaft 68 is equipped at one end with a bevel gear 72' which isin mesh with a bevel gear 73 on a vertical shaft 74' connected at its lower end by a bevel gearing 75 to a crank-handle'76. This gearing operates in the same manner as the winding gear hereinbefore described for winding the curtain 60 back on the roller 61. The shaft Tet is movable by a handle 77 in' the direction of its length to disengage the gears'for the same purpose as the shaft 42 hereinbefore described.

I claim:
